trust me doing that isn't gonna help......awhile ago i did that and i became soo annorexic i was freezing cool all the time, my hair feel out, and i had no energy plus i was loosimg friends cause i wasn't fun anymore and became unusually cranky! doing that caused me to drop to 88lbs! and when i finally decided to eat normally again in 3 months i bounced all the way back up to 115! know how scary that is try and eat healthy food normally, that's my advice
